PIR sensor false trigger and optimal time for delay after PIR detect motion

[sumitrajancse]

Hi,
Its is a very awesome DIY product. Although the PIR sensor trigger false alarm, and the detection distance is very small.
I would recommend using a RCWL 9196 / RCWL-0516 radar motion detector module as it had zero interference with nodeMCU module and greater detection distance.

Also it will be very helpful if you can share you experience on the delay time after a motion is detected (default in the code is 100ms, I guess 2 minutes will be a good time before checking and chanigng the state again.

Please suggest.
